Exclude Reference Types from Bibliography

Is it possible to exclude specific reference types from the automatic generated bibliography?

I’m not clear as to the circumstances warranting this action but you can exclude certain reference types from the bibliography.  You’ll need to modify your output style’s “Bibliography” templates* by deleting the unwanted reference type templates.  (Note: But before deleting it would be helpful to have a backup copy of the output style with all of templates still intact for future use.)

* Go to the EndNote toolbar select EDIT, OUTPUT STYLES, EDIT [name of your style]. In the pop-up style dialog window locate the “Bibliography” heading in the left column then just below click to select “Templates”.
